Figure 2

Neighbor-joining phylogenetic tree constructed with the prophenoloxidase-activating enzyme (lvPPAE1) SP domain and the other 82 clip-domain serine proteinases showing the most similarity in prophenoloxidase-activating proteins in insects. Bootstrap sampling was reiterated 1000 times. The scale bar refers to a phylogenetic distance of 0.1 amino acid substitutions per site. Prophenoloxidase-activating proteins are highlighted in red, and easter-type serine proteases are in green, hemolymph proteases are in blue, and pro-clotting enzymes are in orange. PPAEs in crustaceans are underlined.
